Divided and this application February 12, 1949, SerialNo. 76,098

My invention relates to circular knitting machines and more particularlyto means for protecting the knitted product from oil and the like whichnecessarily accumulates on both the moving and stationary parts of themachine. Such attachments have heretofore been proposed for protectingthe product of a circular knitting machine from grease and oil, butthese are not well adapted for use in the improved machines now commonlyemployed for knitting hose.

It is therefore the object of my invention to provide attachments thatare particularly applicable to circular knitting machines having take-updevices for drawing the knitted product mechanically into a stationarycontainer having a stationary cam projecting from its upper end, andespecially those in which the winding rollers of the take-up mechanismrotate intermittently on their horizontal axles and continuously about avertical axis.

In the drawings accompanying and forming part of this specification, Ihave illustrated my invention as applied to one well-known type ofcircular knitting machines, but it is to be understood that I do notlimit myself thereto.

Figure 1 is an elevation of a portion of a circular knitting machineembodying one form of my invention certain parts being shown in section.

Fig. 2 is an elevation, partly in section, of a portion of the containerprovided with a winding roll bracket slightly difierent in form fromthat shown in Fig. 1.

Figs. 3 and 4 are plan views of the cam oil guards shown in Fig. 2 whichprevent the product from coming into contact with the inner surface ofthe stationary cam while the product is being removed from thecontainer.

In the particular drawings selected for more fully disclosing myinvention and the principles underlying the same, said drawings beingmerely descriptive and by no means restrictive, I I is a bottom needlecylinder of a circular knitting machine, said cylinder enclosing thesinker sleeve l2 within the lower portion of which is disposed the upperportion of a tube l3, said tube terminating in an inverted truncatedcone M, the members 13 and M comprising an inverted funnel-like member,which is shown in the present instance as supported by the bracket. I5.

Preferably, the rim of the substantially coneshaped member [4 isup-turned to form an annular basin for receiving the oil which flowsaround the outer surface of the said funnel-like member. The rim 16 ofthe cone may be proealms. (Cl.66--153) vided with an overflow lip It,ariaim such Icase, a trough it may be placed beneath said lip forconducting the overflow into a receptacle 19. It is desirable that thesubstantiallyl cone shaped member i l be 'disposed immediately above theproduct container 20 and spread outwardly above the open end of thelatter.

Mounted on the top of the container is a winding roller bracket 2| onwhich are mounted for rotation about their axles 22, 22, the takeuprollers 23, 23, whereby the knitted product indicated at 24 is drawnfrom the bottom needle cylinder into the container.

By means of mechanism well understood and therefore unnecessary to beshown, the takeup rollers and their support revolve around a verticalaxis continuously. By means of other mechanism, not shown, the rotationof the rollers 23 about their axles is intermittent, such mechanismbeing controlled by the stationary cam 25 projecting from the upper endof the product container 20.

As oil invariably accumulates on the inner surface of said cam, meansare provided to protect the product while being removed from thecontainer from the oil which collects on the inner periphery of saidcam. One form of such protecting guard is shown at 26, being in thisinstance substantially segmental in shape and provided with a flange 2idepending vertically from its straight edge, such flange being slightlyspaced from the inner surface of the cam. The arrangement is such thatwhen the operator draws the finished stocking or other knitted productfrom the container, the stocking passes over the guard and. does nottake up any of the oil or grease accumulated on the inner surface ofsaid cam.

In Fig. 2, I have shown another form of winding roller bracket to whichare secured the flanged guard above described and a segmental guard 28secured to said bracket approximately diametrically opposite the guard26. In the present instance, the guards are shown attached to thebracket by the screws 26', 28, respectively.

This application is a division of my application Ser. No. 766,606QfiledAugust 6, 1947, upon which Letters Patent No. 2,481,718 wereissuedSeptember 13, 1949.

. Having thus described illustrative embodiments of my inventionwithout, however, limiting the same thereto, what I claim and desire tosecure by Letters Patent is:

1. In a circular knitting machine having a needle cylinder and acontainer into which the knitted product is drawn by rollers having in-.

.3 termittent motion controlled by a stationary cam projecting from theupper end of said container, means for protecting such product from theaccumulated oil on said cam while the product is being removed from saidcontainer, said means comprising a guard overhanging said cam.

2. In a circular knitting machine having a needle cylinder and acontainer into which the knitted product is drawn by rollers havingintermittent motion controlled by a cam, means for protecting suchproduct from the accumulated oil on said cam While the product is beingremoved from said container, said means comprising a segmental guardoverhanging said cam, said guard having a straight edge and flangedepending therefrom, said straight edge being spaced from the interiorperiphery of said cam.

3. In a circular knitting machine having a .needle cylinder and acontainer into which the Iknitted product is drawn byrollers havingintermittent motion controlled by a cam, a winding-roller bracket, meansfor protecting such product from the accumulated oil on said cam 4 whilethe product is being removed from said container, said means comprisinga pair of segmental guards overhanging said cam, one of said guardshaving a straight edge, a flange depending therefrom, said straight edgebeing spaced from the interior periphery of said cam, and the otherguard being secured to said bracket substantially diametrically oppositethe guard first mentioned.
